The new HiSorb product range includes probes and accessories that sorptively extract volatile and semi-volatile organic compounds (VOCs and SVOCs) for analysis by thermal desorption (TD)–GC–MS. They can be used for both immersive extraction from liquids, or headspace sampling from solids. “HiSorb will especially appeal to existing TD users looking ...

Phenomenex Inc., a global leader in the research and manufacture of advanced technologies for the separation sciences, announced today that its Novum™ Simplified Liquid Extraction (SLE) products have been recognized as one of the top innovations of 2015 by R&D Magazine. This is the 10th Phenomenex ...

Phenomenex Inc., a global leader in the research and manufacture of advanced technologies for the separation sciences, announced today the extension of its novel Novum Simplified Liquid Extraction (SLE) sorbent line to include tube formats, in addition to the original 96-well plate formats. Novum is a synthetic ...

The TD-3100 is a low cost benchtop instrument for analyzing hydrocarbons in water and soil. Developed as an alternative to industry standard laboratory methods. Measures samples with solvent extraction methods or non-extraction within solubility limits. Some of the TD-3100 features include: Compaatible with all popular ...

Section 108 of the Consumer Product Safety Improvement Act of 2008 prohibits certain products from containing six specified phthalates. A new ASTM International standard, under the jurisdiction of Committee D20 on Plastics, provides a method for the identification and qualification of these phthalates. The new standard, ...

A White Paper entitled, “Solvent Choices for Infrared Testing of Oil and Grease in Water” was recently published by Wilks Enterprise, Inc. Infrared (IR) analysis is widely used worldwide for determining the amount of oil and grease in water as it is a cost-effective measurement technique that can be easily done on-site or in a laboratory. Since water is a strong absorber in the mid-IR ...

Switchable Solutions Inc. (Switchable Solutions) announced today that Dr. Eric Kelusky and Mary Frazer C.A. have joined the Company's executive team to support accelerating technology commercialization plans. Eric Kelusky has stepped into the role of Chief Technology Officer with Mary Frazer assuming the role of VP Finance and Administration. Switchable Solutions' groundbreaking "Green" solvent ...

This test procedure is used to determine the concentration of BaP extracted from carbon black by the means of a Soxhlet extraction apparatus with toluene. 1. Scope 1.1 This test method covers the qualitative and quantitative determination of only benzo-α-pyrene (BaP), a specific ...

The presence and concentration of oil and grease in domestic and industrial wastewater is of concern to the public because of its deleterious health, environmental, safety, and aesthetic effects. Regulations and standards have been established that require monitoring of oil and grease in water and wastewater. Note 1—Different oil and grease ...

The presence and concentration of oil and grease in domestic and industrial wastewater is of concern to the public because of its deleterious health, environmental, safety, and aesthetic effects. Regulations and standards have been established that require monitoring of oil and grease in water and wastewater. Note 1—Different oil and grease materials may have different ...

The solvent extractables in a wax may have significant effects on several of its properties such as strength, hardness, flexibility, scuff resistance, coefficient of friction, coefficient of expansion, melting point, and staining characteristics. Whether these effects are desirable or undesirable depends on the intended use of the wax. 1. Scope ...

BUCHI Labortechnik has recently received the InterLabTec-Award 2011 for outstanding achievements in the category “chemical-physical analysis“. The prize was awarded for the development of the SpeedExtractor for high pressure extraction in residual analysis. High pressure extraction prevents solvents from entering into the gaseous phase. The new models E-914 and E-916 can extract up to ...

The actual dioxin scandal will result in a strong increase of laboratory work due to severe global regulation by the WHO. The determination of dioxins, especially the extraction process is very time consuming if classical Soxhlet extraction is applied. Pressurized solvent extraction with BUCHI's SpeedExtractor speeds up the extraction process. ...

Refineries and Gas Processing Plants use Glycol to dehydrate oil and gas, reducing the amount of water to less than 0.5%. Once the glycol has dehydrated the hydrocarbon the glycol is “rich” with water and hydrocarbon. In order to reuse the glycol, the water and hydrocarbons are removed in a regeneration process. Normally, a laboratory analysis procedure is used to determine the ...

Varian, Inc. (NasdaqGS: VARI) announced the release of the 7800-AP Sample Preparation System. The 7800-AP is an extremely flexible, fully automated sample purification/preparation system combining advanced robotics, solid phase extraction (SPE), HPLC separation, and collection to deliver purified, concentrated fractions into standard NMR tubes ready for analysis. The system may be adapted to a ...
